OBJECTIVE To evaluate dietary ingredients involved in cartilage and bone metabolism and their influence on osteochondrosis lesions in swine. ANIMALS 80 crossbred gilts (mean initial weight, 39 kg). PROCEDURES Pigs (10 pigs/treatment) were fed a corn-soybean meal basal (control) diet or the basal diet supplemented with additional minerals (copper and manganese or silicon), amino acids (proli...

Migration of intraocular silicone oil, used in the treatment of complicated retinal detachment, has been rarely described, but when it happens it can arise with a differential diagnosis with scleral buckling extrusion, tumor, dermoid, ocular cysticercosis, and abscess. The presence of silicone oil in the eye gives very ugly echographic pictures, but these kinds of pictures can be very useful in...

objective:  the aim of the present study was to evaluate the effect of two impression materials on the shear bond strength of porcelain to immediately sealed dentin. materials and methods: smooth dentin surfaces of 45 extracted premolars were immediately sealed with adper single bond adhesive agent. forty-five porcelain specimens were also prepared. the teeth were divided into one control and t...

We have designed, fabricated and tested a real-time PCR chip capable of conducting one thermal cycle in 8.5 s. This corresponds to 40 cycles of PCR in 5 min and 40 s. The PCR system was made of silicon micromachined into the shape of a cantilever terminated with a disc. The thin film heater and a temperature sensor were placed on the disc perimeter. Due to the system's thermal constant of 0.27 ...

We developed and characterized a novel picoliter droplet-in-oil array generated by a double-inkjet printing method on a uniform hydrophobic silicon chip specifically designed for quantitative polymerase chain reaction (qPCR) analysis. Double-inkjet printing was proposed to efficiently address the evaporation issues of picoliter droplets during array generation on a planar substrate without the ...

  Three different materials (aluminum, ferro -silicon and silicon) were used as antioxidants in order to prevent the decarburization process and to keep and/or increase the final properties in MgO-C refractories. Their effects were compared by measuring the physical and mechanical properties as well as oxidation and the resultant phases and microstructures, in the temperature range of 200-1600 ...

Microcapsules containing the aqueous solution of Azur B of a water soluble dye were prepared with the melting dispersion cooling method and applied to the amplification detector of plant DNA. Paraffin wax with melting temperature of 75 ̊C was used as the shell material. In the experiment, the aqueous solution (W) of Azur B as the core material was dispersed in the melted paraffin wax (O) to form...
